|Frame size question..||Sawman|
Nov 30, 2001 2:57 PM
|I have been mountain biking for a long time but also like road riding but am tired of doing it on my road bike. I am buying a 2001 Bianchi Campione on the net and am not sure of the correct size. I am 5'7" with a 29" inseam. I am considering a 51 or a 53cm. Any input is greatly appreciated.

|... sounds a little shortish...
Are you getting an accurate cyclist's inseam measurment?
this is not the same as a tailor's.

|I am 5'8" with 30" inseam and I ride comfortably with 50cm c-t-c. I've tried 52 ~ 54 cm before and they were just too big to be comfortable.
You may want to go with 50cm or even smaller, and with 170mm crank.

|A 5'-7" rider will generally find the top tube too short on a 50cm, even measured c-c. This poster should look to buy the largest (and longest TT) frame that he can straddle to get 2cm of standover clearance in bare feet.
I'm 5'-7" (almost), with a 32-5/8" inseam. I ride a 55cm (c-t) with a 110 stem. If I were to ride a 50cm, I'd need a 130 or 140 stem, even with my shorter torso.

|But considering that his inseam is only 29" (and mine is 30"), there is no way that he could ride a frame larger than 54cm c-c. For him (as well as myself) a 2cm standover clearance can only be achieved on a 48~50cm frame.
Yes, you are right that a longer stem is needed. I need a 12cm stem. For the poster, if he rides a 50cm frame, he may need a 11~12cm stem.
I may be more conserative. If I cannot be perfectly fit on a bike, and I don't want go for a custom one, I rather have a smaller frame than a larger one.

|Hey, I was measuring my inseam incorrectly. 29" is my tailor inseam. My cycling inseam is 31.5 and that puts me on a 53cm frame according to the size computations on wrenchscience.com page. I also went to my LBS and rode a 51 and 53. The 51 was just too short of a top tube, felt more comfortable on the 53. Thanks for everyones help. I'll post a followup after I put some miles on the frame.|

|If your measurements are correct I'd suggest starting with a 52-53cm CT frame. Make sure you don't get a too small frameset as the saddle to bar drop may become problematic. I think the 51cm CT would be too small. I.e. ideally, you want a frame with 1cm or less of spacers under your threadless stem. If you size the frame by this criteria and a comfy TT length you should be "good-to-go".

|Go check out ( www.wrenchscience.com ) for a great online size tool. It will recomend the ideal frame size, overall reach and handle bar width.|| |
